Process Analyzer Sample Probe Assembly (SPA)with Conax Packing Gland (PG) Compression Seal Fitting

For Unique Applications...• Process analyzing • Flare stack emissions• Chemical injection quills• Waste water analysis• Potable water quality sampling• Hot tapping liquid or gas streams

Features & Options...• Plasma welded stop collar• Optional Retaining Chain Kit• Wake frequency calculations• Various probe ends and valve

types available

Sample Probe AssemblyThe Conax Technologies’ Sample Probe Assembly (SPA) is used to hot-tap a probe into a process through a process isolation valve.

Temperature and Pressure RatingsRefer to the appropriate sections of Conax Catalog 5001C for temperature and pressure ratings for static conditions. Pressure ratings are reduced when the sealing gland cap is loosened to allow for the insertion or extraction of the Sample Probe.

Material Options• Optional materials for the Sample Probe Assembly

and the Conax Technologies’ Packing Gland (PG) body (wetted components) are available. Available options include 316L SST, 316 NACE SST, 316L CRN, Monel 405, Hastelloy C276 and Inconel 600.

• Sample Probe Assemblies and/or PG Gland bodies can be supplied with a Silcolloy™ 1000 (Silcosteel®-CR) or SilcoNert™ 2000 (Siltek®/Sulfinert®)coating.

• Standard Sealants are Teflon®, PEEK™, and Grafoil®. Other sealants are available for special applications.

Sample Probe Assembly • The end user must take the necessary safety precautions when loosening the cap of the Conax sealing gland when inserting

or extracting the Sample Probe into pressurized environments. • The end user is responsible to control any leakage of process that may occur during insertion or extraction of the Sample

Probe. • The end user is responsible for determining the appropriate Sample Probe material, diameter and wall thickness for the

process environment and flow rates. • Conax Technologies is not responsible for the operation of the Conax Packing Gland (PG) assembly once the cap is

loosened to allow for the insertion or extraction of the Sample Probe. • Typically, when properly installed, the angled Sample Probe tip should have the long side upstream. This reduces the

particulates entering the Sample Probe and into the process analyzer filter. • The Sample Probe immersion length should be designed to obtain a process sample close to the center third of the pipe.• It is suggested that the end user mark the Sample Probe end with an indelible ink marker relative to the angled end for

proper orientation into the process.

Retaining Chain Kit• Retaining chain assembly is not intended to assist or control the insertion/extraction of the sample probe. The operator is

responsible for restraint of the sample probe at all times. • Chain must be kept as short as possible to function properly. Some minor slack in the chain will be present when sample

probe is inserted. The retaining chain kit is not intended for impact loads. If it is subject to an impact load, all parts must be inspected/replaced as required.

• Periodically inspect restraint system. Re-torque probe collar and threaded connector. Replace parts as necessary. • Maximum design pressure for the retaining chain kit is 500 psig. (≤ .500” (12.70mm) Sample Probe diameter.)• Prior to installing the SPA gland into the process valve port, install the front retaining washer over the PG gland pipe thread.
